Kurapa kupisa inzira inokosha mukugadzirwa kwemaindasitiri. Izvi zvinosanganisira kupisa nekutonhodza zvikamu zvesimbi kuti zvivandudze hunhu hwazvo hwemuchina, hwakadai sekuoma, kuomarara uye kuramba kupfeka. Zvisinei, hazvisi zvese zvinorapa kupisa zvakagadzirwa zvakaenzana. Zvimwe zvinogona kukonzera kukanganisika kwakanyanya kana kutokuvadza zvikamu. Apa ndipo panoshanda maovheni anodzima mweya wevacuum.
Chitofu chinodzima mweya wevacuumrudzi rwemuchina wekurapa kupisa, unoshandisa gasi rine simba guru kupisa zvikamu mu vacuum wozozvitonhodza. Vacuum inogadzirwa kudzivirira chero oxidation kana kusvibiswa kuti zvisaitike, uye gasi (kazhinji nitrogen kana helium) rinoshandiswa kudzima chikamu nekukurumidza uye zvakaenzana.
Kudzima simbi ne vacuum quenching kunoonekwa seimwe yenzira dzakanakisisa dzekuwana kuenzana kwakanakisa kwekuomarara uye kusimba muzvikamu zvesimbi. Kunogadzira chimiro chakanaka chisina kubviswa kana kushanduka kweganda, zvichikonzera hunhu hwakanaka hwemakanika uye hupenyu hurefu hwebasa. Pamusoro pezvo, maovheni ekudzima simbi ne vacuum quenching anogona kubata zvinhu zvakasiyana-siyana, kubva kusimbi nesimbi isina ngura kusvika kuaruminiyamu ne titanium alloys.
Kuti uwane mabhenefiti akazara ekushandisa vacuum harding, unoda nzira yakavimbika uye inoshandachoto chinodzima vacuumChitofu chakanaka chinofanira kuva nehunhu hunotevera:
- Vacuum yakakwirira: Zvakanaka kuti choto chikwanise kuva ne vacuum ye10^-5 Torr kana pasi kuti kuderedze oxidation uye kusvibiswa.
- Kudzima nekukurumidza: choto chinofanira kukwanisa kutonhodza chikamu pa10-50°C/s kuti chiwane chimiro chaunoda.
- Kugoverwa kwekupisa kwakafanana: Choto chinofanira kunge chine sisitimu yekudziyisa yakagadzirwa zvakanaka iyo inogovera kupisa zvakaenzana muchoto chose kuitira kuti mhedzisiro yekudzima irambe iripo.
- Sisitimu yekudzora yepamusoro: Choto chinofanira kunge chine panel yekudzora iri nyore kushandisa inobvumira kudzora tembiricha chaiyo uye kuyerera kwegasi, pamwe nekutarisa nekunyora data rekuita.
At PaijinTinopa mhando dzakasiyana dzemafuroni ekudzima vacuum anosangana nezvinodiwa izvi nezvimwe. Mafuroni edu akagadzirwa uye akavakwa achishandisa tekinoroji yazvino nezvinhu nechikwata chine ruzivo chemainjiniya nematekiniki. Tinopawo mhinduro dzakagadzirirwa iwe kuti dzisangane nezvinodiwa zvako.
Mamwe emamodeli edu anozivikanwa zvikuru anosanganisira:
- Chitofu chinodzima mhepo chevacuum chakamiswa: chitofu ichi chinogona kubata zvikamu zvinosvika 2000mm pakureba uye 1500kg pakurema, nekupisa kwakanyanya kwe1350°C uye kutonhora nekukurumidza kwe30°C/s.
- Furnace inodzima mhepo ine vacuum yakatambanudzwa: Furnace iyi inogona kugadzirisa zvikamu zvine dhayamita yepamusoro ye1000mm nehuremu hwe1000kg, ine tembiricha yepamusoro ye1350°C uye mwero wekutonhora nekukurumidza we50°C/s.
- Choto chevacuum chine mabasa akawanda: Choto ichi chinogona kushandiswa pakurapa kupisa kwakasiyana-siyana kwakadai sekudzima vacuum, tempering, annealing, brazing, nezvimwewo, netembiricha yepamusoro ye1300°C uye vacuum degree ye10^-5 Torr.
Mukupedzisa, magumbeze ekudzimisa mweya wevacuum chishandiso chakakosha chekuwana mhedzisiro yekurapa kupisa kwemhando yepamusoro uye nguva dzose. Anoita basa rakanaka, kushanda zvakanaka uye kushanduka-shanduka zvichienzaniswa nedzimwe nzira dzekurapa kupisa. Kana uchitsvaga furnace yakavimbika uye inoshanda zvakanaka, tarisa mhando dzePaijin dzeVacuum Air Quenching Furnaces nhasi!
